For those who are unaware (like I was), the CFI was originally patented as an interchange. It looks insane, however according to Wikipedia, it was built, as he received money from people using his design. I was wondering if it really was built, or if Wikipedia is wrong. I kinda hope it was built, because it looks weird/awesome/convoluted.
I build roads on Minecraft. Like, really good roads.
Interstates traveled:
4/5/10*/11**/12**/15/25*/29*/35(E/W[TX])/40*/44**/49(LA**)/55*/64**/65/66*/70°/71*76(PA*,CO*)/78*°/80*/95°/99(PA**,NY**)

*/** indicates a terminus/termini being traveled
° Indicates a gap (I.E Breezwood, PA.)
